What is the executive branch?

The executive branch is the part of the federal government responsible for carrying out and enforcing the laws passed by Congress. Created by Article II of the Constitution, the executive branch is led by the President of the United States and includes the Vice President, the Cabinet, the executive office of the President, federal agencies, and the United States military. The executive branch employs roughly 4 million people, including military personnel and civilian federal workers, making it by far the largest of the three branches of government.

Article II vests the executive power of the United States in a President. The framers debated whether to have a single executive or a council, ultimately choosing one President to ensure clear accountability and decisive leadership. The President is both head of state, representing the United States in ceremonial and diplomatic functions, and head of government, directing the operations of federal agencies.

The executive branch carries out laws through 15 Cabinet-level departments and dozens of independent agencies, commissions, and bureaus. The Cabinet departments include State, Treasury, Defense, Justice, Interior, Agriculture, Commerce, Labor, Health and Human Services, Housing and Urban Development, Transportation, Energy, Education, Veterans Affairs, and Homeland Security. Each is led by a secretary appointed by the President and confirmed by the Senate.

Beyond enforcing laws, the executive branch has significant constitutional powers of its own. The President serves as Commander in Chief of the armed forces, conducts foreign policy, negotiates treaties (subject to Senate ratification), appoints federal judges and senior officials (subject to Senate confirmation), grants pardons for federal crimes, and can issue executive orders directing how laws are carried out. The President also has the power to veto bills passed by Congress.

The executive branch has expanded substantially since the founding. Early presidents had small staffs and few agencies. The growth of federal regulation in the 20th century, particularly during the New Deal and Great Society, created the modern administrative state. Today the federal government regulates everything from air travel to food safety to financial markets, much of it through executive branch agencies operating under congressional authorization.
